Create an invoice

  1. 1Step 1: Go to Sales > Invoices and choose + New (on a phone, New > Invoice).
  2. 2Step 2: Pick the customer from your customer list. Each customer's ID shows beside the name to tell similar names apart. Customers must be in the list first: see Customers.
  3. 3Step 3: Check the invoice date and the payment terms. The terms set the due date.
  4. 4Step 4: Check the place of supply, filled in from the customer. It decides the tax.
  5. 5Step 5: Add lines: pick an item from the catalog, scan it, or type a one-off item. Enter the quantity, and change the rate, discount or GST rate if needed.
  6. 6Step 6: Add an order number, notes, terms or an adjustment if you need them.
  7. 7Step 7: Choose Save to issue the invoice, or Save as Draft to finish later.
PartHow it works
Payment termsDue on Receipt, or Net 7, 15, 30, 45 or 60 set the due date, and changing the invoice date moves it. Type your own due date and the terms switch to Custom. The due date can't be before the invoice date.
LineQuantity × rate per unit, less a discount in rupees or percent, plus one GST rate. Picking a catalog item fills in its HSN/SAC, unit, rate and GST.
SalespersonOne of your organization's users. Starts as you.
AdjustmentAn amount taken off the total, for example to settle on a round figure.
Round-offWhen Settings > Invoice turns it on, the total rounds to the nearest rupee and the round-off is shown.

If something is missing, Save lists what to fix. A saved invoice needs every line to have an item, a quantity above zero and an amount; a draft needs only the customer and the date.

GST and place of supply

  • The place of supply is filled in from the customer: their shipping state, then billing state, then GSTIN. You can change it.
  • Biththi compares it with the state in your GSTIN: the same state charges CGST + SGST, another state charges IGST at the full rate. The form shows which applies.
  • If your business has no GSTIN, invoices are a Bill of Supply with no tax.
  • A saved invoice keeps its tax treatment unless you change its place of supply.

Drafts and invoice numbers

  • A draft gets a reference such as DRAFT-12 and doesn't use up an invoice number.
  • Saving gives it the next number in your series (1, 2, 3 and so on), so deleting a draft never leaves a gap.
  • Drafts don't change stock and don't count towards your plan's saved-invoice limit.
  • After saving, the invoice opens ready to print or share.

After saving

  • A saved invoice is final: it can't be edited, and it takes product quantities out of stock.
  • Its payment status shows as Paid, Part paid, Unpaid or Overdue, from the payments and credit notes against it.
  • On the invoice: Record payment, Apply advance (when the customer has paid ahead) and Issue credit note. See Receivables.
  • A saved invoice can be deleted only when Settings > Invoice allows it, and never once it has payments or credit notes.

Print and share

  1. 1Step 1: Open the saved invoice and choose Print.
  2. 2Step 2: Choose Save as PDF to print or save a PDF, Download as PNG for an image, or Copy as PNG to paste it into a chat or email.

The printed invoice is headed Tax Invoice, or Bill of Supply without a GSTIN. It shows both GSTINs, the place of supply with its state code, a summary by HSN/SAC code, the total in words, your payment details with a UPI QR code for the balance due, a Paid, Part Paid or Payment Pending stamp, and your signature.

Tip: Printing needs your business name, address and phone in Settings > Business. In Chrome or Edge, turn off Headers and footers in the print dialog to keep the page address off the PDF.
Growth plan: Starter invoices carry a small Biththi watermark. On Growth you can turn it off in Settings > Invoice.

Clone an invoice

Growth plan: On Growth, Clone creates a new invoice with all the details of the one you're looking at. Useful for repeat orders.

The Starter limit

On Starter you can save 25 invoices in total. Drafts are unlimited. Saving a 26th invoice shows an upgrade message and nothing is saved, so no number is used up. See Plans.
